Before the boat turned over, the men fired a flare that was seen by a woman in Juno Beach. She called the Coast Guard, which sent a 41-foot boat and a helicopter to look through the night for the missing fishermen.

The survivors said they saw the helicopter fly overhead several times, and one man said he yelled until he was hoarse to try to attract the pilot's attention. They said the helicopter's light never landed on them.

At 8:35 a.m. Monday, a fishing boat spotted the four survivors.

They told the Coast Guard that a large wave caused their boat to capsize. The fishermen were wearing life preservers and they held on to the overturned boat. One man said he held on to the outboard motor, and the others said they held on to the side.

They said waves kept pushing them away from the boat, and they had to swim back to it each time.

They said the victim appeared to be fine at first, but about 4 a.m. he began having trouble breathing. One survivor told the Coast Guard he was holding on to the belt of the victim's life jacket, and the victim was staring into space. The man said he slapped the victim several times in the face but could not revive him.

A short time later, the belt on the victim's life jacket broke and the man floated off. The Coast Guard said it was still looking for his body.

The four survivors were tired and shaken when rescued but did not need medical attention, Williams said.

The five men left West Palm Beach at 9:30 p.m. Sunday in hopes of catching kingfish off Juno Beach.
